Letters Patent No. 114,173, dated April 25, 1871.

iiPROVEivlENT IN DUMPlNG-WAGONS.

The Schedule referred to in these Letters Patent and making part of thesame.

This invention relates to four-wheeled-dumpingwagons constructed todischarge the load at the rear,

in which the body oscillates on an axis located between the wheels, andin which the rea-r axle is cranked to admit ofthe tilting of the body.

Our improvement consists in the arrangement of the cranked portion ofthe rear axle, which `is turned to stand at an angle of about forty-fivedegrees to a vertical line drawn through the axis of its journals, forthe purpose ofjenabling it to pass over all ordinary obstructions in theroad Without necessitating the uudue elongation of the crank, whichresults if the axle be turned up to a horizontal position, as in thelatter case such axle must extend forward at leastA to the point wherethe body is pivoted.

' To enable those skilled in the art to make `and use our invention, wewill proceed to describe its construction and operation.

The frameA of the wagon is mounted upon four wheels, the front ones ofwhich are suciently small to be turned under it, the frame at this endbeing attached to the front axle by means of holsters and the ordinaryfifth-wheel, in the manner shown.

At A', between the front and rear axle, the frame hasa stout cross-bar,which, together with the bolsters at the front end, form support forthe'body B of the wagon when in the position shown in fig. 1 in fulllines.

The frame in rear of the cross-bar A has no trans verse beams to permitthe body toV tilt between its sides.

The body B is hinged upon a stout transverse bolt or shaft, B', arrangedin the frame directly in rear of the cross-bar A', where its weight,when loaded, is about balanced.

'To prevent the Vunseasonable tilting of the body its forward endcarries a hook, la, by which it may be secured to a staple, l1', on thebolsters. dinary devices may, however, be used for this purpose.

To clear the body in dumping the load the rea-r axle C is cranked andturned forward until its cranked portion stands at an angle offorty-live degrees, -more or less, to a vertical line drawn through theaxis of its journals. In this position ,it is firmly secured by braces Cto the frame.

We do not claim broadly a cranked rear axle in fourwheeleddumping-wagons, as cranked axles haveV been employed in this connection.But, in all cases, such cranked axle has been arranged either to hangdown vertically or in a horizontal position. The former arrangement isVobjectionable, because the axle hangs down too low, coming so near tothe surface of' the road that it will not clear ordinary obstructions,while the latter arrangement requires that the axle should be crankedfar enough to extendforward to the point where the body is hinged, thusmaking the crank undulyA long, and, consequently, weakening the axle. Byour arrangement these objections are all overcome.

What we claim as our invention, and desire to secure by Letters Patent,is`

In a four-wheeled dumping-wagon, the cranked rear axle C, but only whenits cranked portion is turned forward to stand about midway between ahorizontal and Vertical position, in the manner and for the purposeshown and described.
